The new 1.5V, 1.8V and 2.5V models in DATEL’s flagship 9-15 Watt A-Series

can source a continuous 6 Amps. This is the most "low-voltage" current available

from a standard 1" x 2" package, and these power converters exemplify DATEL’s

relentless drive to bring you more power/current, from standard packages, without

compromising reliability or resorting to thermal specmanship.

By combining a high-frequency (310kHz), high-efficiency (to 88%), synchronous-

rectifier topology with the newest components and time-tested, fully automated,

SMT-on-pcb construction, these UWR Models are able to bring you 9-15W (@ up

to 6A) in the standard 2" x 1" package from which most competitors can only get

5-10W (@ 3-4A). All UWR’s deliver their full output power over ambient temperature

ranges from –40°C to as high as +70°C (model and input voltage dependent) without

heat sinks or supplemental forced-air cooling. Devices derate to +100°C.

Output voltages are 1.5, 1.8, 2.5, 3.3, 5, 12 or 15 Volts. Input voltage ranges

are 10-18V ("D12" models), 18-36V ("D24" models) or 36-75V ("D48") models. All

models feature input pi filters, input undervoltage and overvoltage lockout, input

reverse-polarity protection, output overvoltage protection, output current limiting, and

continuous short-circuit protection. On/off control, sync, and output-trim functions are

optional (see Optional Functions). All models are certified to IEC950, UL1950 and

EN60950 safety requirements for OPERATIONAL insulation. "D48" models (36-75V

inputs) are CE marked.

UWR 9-15W DC/DC’s are packaged in low-cost, light-weight, diallyl phthalate

(UL94V-0 rated) plastic packages with standoffs. EMC compliance is achieved via a

low-noise design rather than through expensive metal shielding.
